DEVICE FOR HOLDING HOGS SNOUTS.

SPECIFICATION forming part of Letters Patent No. 460,222, dated September 29, 1891. Application filed January 28, 1891- Serial No. 379,446. (No model.)

To all whom it may concern:

Be itknown that I, HARVEY HAMMOND SILs- BY, a citizen of the United States, residing at La Cygne, in the county of Linn and State of Kansas, have invented a new and useful Device for Holding Hogs Snouts, of which the following is a specification.

This invention relates to an improvement upon Patent No. 422,0l1, granted me February 25, 1890, for a device for holding hogsnouts and severing the tendons therein, whereby the efficiency of their rooters is destroyed.

The objects of my present improvement are to provide means for compressing the flesh and tendons of the snout, so that the tendons are held more rigidly while the cut is being made; furthermore, to simplify the construction by forming the knife-support and stock for the knife in a single piece and avoiding the use of the many screws, &c., and, finally, to improve the construction of the cutting-edge of the knife.

Other objects and advantages of the inven* tion will appear in the following description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a combined snout-holder and tendon-cutter embodying my improvements. Fig. 2 is a side elevation, the device being in position to grip the snout of a hog. Fig. 3 is a detail in perspective of the knife-carrying plate. Fig. at is a detail in perspective of the knife. Fig. 5 is a detail perspective view of a portion of the implement inverted to show the shape of the lateral extension.

Like numerals of reference indicate like parts in all the figures of the drawings.

The holder comprises the opposite members 1, which cross each other and are pivoted, as at 2. Each member in rear of its pivot is curved to form suitable handles and in front of the pivot to form curved jaws The upper curved jaw 3 is extended at its outer side by means of a concaved plate 4., preferably formed integral with the jaw and provided with an opening 5 opposite the outer face of the jaw.

G designates a sheet-metal plate formed of brass, steel, or iron, and in this instance secured by a screw 7 to that member of which the upper jaw is apart, in rear of the fulcrum or point ofpivot of the two members. This plate, if desired, may be secured to the pivot employed to fasten the two members together. The front end of the plate is provided with a depending hooked portion 8, the end of which is sharpened to a cutting-point 9. In rear of the hook the upper edge of the plat-e is provided with a lateral extension 10, of U shape, which passes over the upper side of the jaw and down the outside of the same to the opening 5, where it terminates. The extensionis provided with aslot 12, and through the sameinto the upper jaw passes a set-screw 14, which is embraced by the bifurcations of a flat spring 15, the rear end of which is by a screw 16 secured to the upper side of the upper jaw. The inner edge of the upper jaw is provided with a recess 17 opposite the outer end of the metal plate, and opposite said recess said plate passes through a slot 18, formed in the lower end of a lever 19, so that a portion of the lever rests in the slot of the jaw, as will be apparent. A bearing -screw 20 passes through the lever and the plate, and below the same said lever is provided with opposite parallel beveled cutting-edges connected at their lower ends by a U-shaped cutting-edge. The cutting-edges 21 out against the sides of the fixed cutter formed at the front or outer end of the metal plate, while the V-shaped cutter 22 operates against the lower beveled end of said plate. By operating the regulating-screw the plate may be forced nearer the jaw or supported farther therefrom, so that its fixed cutter may extend a greater or less distance below the under side of said jaw, and hence penetrate farther into the snout of the hog.

In operation the regulating-screw is first rotated, so as to adapt the device for cutting deeper or shallower, in accordance with the age of the. hog, after which the members are separated at their rear ends or handles and the jaws opened or spread and introduced over the rooter of the hog. The handles are now brought together, so as to firmly clasp or clamp upon the rooter or snout, and in so doing the beveled cutting end of the rigid or fixed knife at the outer end of the plate is forcedinto the snout at one side of the tendon. It now simply remains to swing the handle or lever of the movable cutter to the rear or toward the operator, when the V-shaped cutter of the movable knife will be forced into the snout at the opposite side of the tendon, and after arriving in contact with the same will pass under it, the opposite beveled edges serving to form two outs in the tendon, and thus remove a section of the same, whereby it is prevented from reknitting and permanently disables and renders inefficient the root-er of the hog.

The lever-carryin g knife is not pivoted concentrically with the curvature at the end of the plate, and hence the upper end of the recess of the knife or lever coming in contact with the edge of the plate serves to act as a stop for the swinging movement of the lever. At the same time the rearward movement of the lever may be arrested by the same coming in contact with the lateral extension or arm.

By reason of the fiangeor extension 4 the rooter of the hog is depressed and the tendons operating said rooter are raised and stretched, so that they are the more easily engaged by the knife passing thereunder. When the device is clamped upon the snout, the knives are opened and are sunk into the flesh at each side of the tendons, so that by operating the lever of the movable knife an oblong piece is removed.

I-Iaving described my invention, what I claim is 1. In a tool of the class described, the combination, with the opposite pivoted members terminating in curved jaws, of a plate secured to one of said jaws and located at one side of the same, said plateterminating at its front end in a depending fixed knife, and a movable knife pivoted on the plate and adapted to operate against the fixed knife, substantially as specified.

2. In a tool of the class described, the combination, with the opposite pivoted members terminating in curved jaws, of a plate secured to one of'said members, terminating at its frontend in a depending fixed knife and provided with a lateral extension having a perforation, an adjustment-screw mounted in the perforation and the jaw, and a movable knife pivoted to the plate and adapted to operate against the fixed plate, substantially as described.

3. In a tool of the class described, the combination, with the two opposite pivoted members terminating in curved jaws, of the metal plate secured to one of the jaws at the side thereof, said plate terminatingat its front end in a depending fixed knife and provided in rear of the same with a lateral extension embracing the jaw and provided with a perforation, a spring secured to the jaw and terminating under the extension, a set-screw mounted in the perforation, spring, and jaw, and a knife pivoted to t-heplate and adapted to operate against the fixed knife, substantially as specified.

4. In a tool of the class described, the combination, with the opposite pivoted members terminating in curved jaws, one of which is extended laterally .beyond the other in the form of a concaved flange and provided with a perforation adjacent to the jaw, said jaw at its opposite side being provided with a recess, of a metal plate secured to the jaw at the recessed side thereof and terminating at its front end in a depending beveled knife and in rear of the same provided with a lateral angular extension embracing said jaw, a fiat spring secured to the jaw and terminating under the extension, a set-screw loosely mounted in the spring and extension and terminating in the jaw, and a knife provided with a recess through which the plate is passed and pivoted near the end of the plate, said knife being provided with opposite beveled side edges and a lower V-shaped edge, substantially as specified.

5. In a tool of the class described,the combination, with the opposite pivoted members terminating in curved jaws, of the curved flange or extension 4, attached to one side of one of the jaws and projecting laterally outward therefrom and adapted to depress the rooter of the hog, and the cutting-tool located on the opposite side of the same jaw, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
